And not everyone who works there understands about firearms. I just remembered a story a friend told one time (he works as a manager with a larger truck shipping company). They had a pallet with, I think it was FAL, build kits but they did not contain a receiver just everything else. The dock workers didn't want to ship the pallet as they thought it contained actual firearms, not just parts (trying to follow regs). My friend had to open the pallet and one of the kits to roughly assemble the thing so that they could see that it was not a complete firearm. They then boxed the whole thing back up and sent it on its way.
